Before beginning the Unit weight of construction materials table list.  Let’s start with the basics.

### What is the Unit weight of a Material?

Unit weight of the material is simply defined as Mass per Volume (M/V) and also it is called Specific Weight or Density.

Density = M/V

### Purpose of Knowing the Unit Weight

Estimations are always not as simple as it looks.

Sometimes we will get a material calculation in different units.

For example, while calculating the cement mortar ratio for plastering we will get the weight of cement in m3 or cubic feet.

However, while buying the cement in stores we need to calculate the number of bags.

By knowing cement unit weight 1440 Kg / m3. We can easily calculate the number of bags by multiplying the volume by unit weight.

If it is 0.3 m3 then we can calculate the number of bags =0.3 X 1440 = 432 Kg = 8.64 or 9 Cement Bags

Don’t forget the unit weight or density will differ based on location & type of material.
